I live in the UAE, inland about 70 miles. It's hot here. We're already hitting 105 F everyday. In July and August it hits 120+ F every day, without fail. I've been mixing for 3 years. I keep all my stuff, except nic, in closets. If I'm not in the room the A/C is off and at the hottest the rooms can hit 100+, no problem. The summer lasts 6 months here. I've yet to have anything go bad due to heat. I have some flavors I haven't used in a couple of years that may be bad, but I don't use them so no worries there. Yes, I'm very accustomed to this heat after 21 years. I could never live in New England again.
